Synthetic Spider Protein Future Of Anti Venoms
2013-05-10 08:51:22

April Flowers for redOrbit.com - Your Universe Online Scientists say they have engineered a spider protein that could be the start of a new generation of anti-venom vaccines, with the potential to save thousands of lives worldwide. Researchers from the Universidade Federal de minas Gerais in Brazil say the new protein, created from parts of the toxin from the reaper spider, may be a promising candidate for developing therapeutic serums or vaccines against other venoms. Part of a family...

Male Black Widows Cannibalize Older Females
2013-05-07 05:18:27

Alan McStravick for redOrbit.com - Your Universe Online The idea that the female of a species would, after completing coitus, approach, kill and eat her mate is a sentiment that instills, if not fear, unease in many the male reader. This scenario, in fact, is exactly how the Black Widow spider got its name. However, according to researchers out of Masaryk University in the Czech Republic, the popular knowledge behind this spider might not necessarily be so. Study authors Lenka Sentenska...

Fascinating Examples Of Genetic Engineering
2013-04-29 09:27:47

Rayshell Clapper for redOrbit.com - Your Universe Online After learning about human genetic engineering, many readers might want to find out about some examples of genetic engineering. Both bizarre and beneficial, the following article highlights some truly fascinating and pragmatic examples of modern genetic engineering. The Biotechnology Forums, a website for professionals and students in biotechnology (the area that studies genetic engineering) recently explained some of these...

Butterfly Evolution Can Also Be Driven By Spiders
2013-03-13 05:09:24

April Flowers for redOrbit.com - Your Universe Online Butterflies are vibrant and colorful insects, with colorations designed to deflect predators. A new study from the University of Florida reveals that some of these predator driven defenses may be caused by enemies one-tenth the size of the butterfly. Since Darwin sailed on the Beagle over 150 years ago, scientists have theorized that the main influence on the evolution of coloration in butterflies came from large predators such as...

A Real Spider-Man Could Stop A Moving Train, Study Shows
2013-02-25 19:50:12

Lee Rannals for redOrbit.com — Your Universe Online Movies and comic books are primarily based on fantasy, but a new study shows how one particular concept involving Spider-Man might be more feasible than most superpowers. University of Leicester physics students found Spider-Man's webbing strength would hypothetically be strong enough to stop a moving train. In the movie Spider-Man 2, the Marvel comic character uses his webs to help stop a runaway train before it plummets off...

Bio-Inspired Materials Leading To Greater Engineering
2013-02-16 10:56:29

Lee Rannals for redOrbit.com — Your Universe Online Bio-inspired, man-made materials may one day offer up designs that are more lightweight, tougher, and stronger than other options out there. A team writing in the journal Science say they have identified characteristics of biological materials they think engineers will be able to emulate in future materials. Two engineers at the University of California, San Diego examined three characteristics of biological materials, including...

Researcher and team are the first to measure all of the elastic properties of an intact spider's web, drawing a remarkable picture of the behavior of one of nature´s most intriguing structures. The work could lead to new “bio-inspired” materials that improve upon nature. As fibers go, there´s never been anything quite like spider silk. Stretch it. Bend it. Soak it. Dry it out. Spider silk holds up. It is five times stronger than steel and can expand nearly a third...

Predator Wasps Disguise As Ants To Hunt And Capture Prey
2013-02-04 12:36:11

Pensoft Publishers Two wasp species, Calymmochilus dispar and Gelis apterus, have been recorded as parasitoids on ant-eating spiders in a study published in the open access journal ZooKeys. The host spider, Zodarion styliferum, belongs to the largest genus of predominantly ant-eating spiders. Their distribution area includes Europe, Asia and North Africa, significantly with at least 35 species reported for the Iberian Peninsula only, marking a record in numbers in Portugal, where this...

Understanding The Mysteries Of Spider Silk
2013-01-28 19:02:43

Lee Rannals for redOrbit.com — Your Universe Online Scientists are unraveling the mysteries of what makes the fiber that spiders spin five times as strong as piano wire. A team from Arizona State University found a way to obtain a wide variety of elastic properties of the silk from several spiders' webs using non-invasive laser light scattering techniques. "Spider silk has a unique combination of mechanical strength and elasticity that make it one of the toughest materials we...

Cobweb Spider, Theridiidae
2014-06-23 08:44:11

Theridiidae is a family that contains over 2,200 species of cobweb spiders, also known as tangle-web spiders or comb-footed spiders, which can be found throughout the world. This species received its common names from its tendency to build three dimensional, sticky webs and from the comb of serrated bristles on the fourth leg. It is thought that this family is the only to hold a high diversity of web types, including gumfooted webs, which are highly similar to those produced by spiders in the...

Wolf Spider, Lycosidae
2014-06-23 08:30:31

Lycosidae is a family that holds about 2,300 species of wolf spiders that can be found in a variety of habitats including woodlands, gardens, and moist coastal areas. Many species do require specific microhabitats, like montane herb-fields, but most species are nomads and do not reside in one area for long periods of time. Some species within this family build burrows that can have trap doors or open entrances, while others in arid regions build nests with plugged entrance ways, to protect...

Funnel Weavers, Agelenidae
2014-06-19 13:16:37

Agelenidae is a family that holds about 1,200 recognized species of funnel weaver spiders that occur throughout the world. These spiders build funnel shaped webs that trap prey in their complicated patterns, but they should not be confused with other families of spiders that build funnel webs like funnel-web spiders or funnel-web tarantulas. Funnel weavers can reach an average body length between .1 inches in the smallest species and .7 inches, although the largest species can reach total...

Sparassidae is a family that holds over one thousand species of huntsman spiders, also known as giant crab spiders and wood spiders, or as rain spiders or lizard-eating spiders in some areas of its range. These species are native to Australia but were also introduced to temperate areas throughout the world including China, Japan, and some areas of the United States, including Florida and Hawaii.

Thomisidae is a family that holds around two thousand species of crab spiders that can be found throughout the world. Although the name crab spider has been used to refer to a large number of species, it is most often used to refer to members of this family, especially the flower crab spider. Many members of this family have flat bodies that resemble those of crabs and others hold their two front legs in positions that crabs are known for or move in sideways motions as crabs do. Although...
